In the film "The Matrix," Neo goes to see the Oracle and in her kitchen above the door is a two-word phrase which the Oracle suggests translates to 'know thyself.' What was this phrase and why is it, therefore, incorrect?

The Ancient Greek aphorism "Know thyself", Greek: γνῶθι σεαυτόν gnōthi seauton (also ... σαυτόν ... sauton with the ε contracted), was inscribed in the pronaos (forecourt) of the Temple of Apollo at Delphi - according to the Greek periegetic (travelogue) writer Pausanias (10.24.1).... In Latin, the aphorism is generally given as nosce te ipsum[2]. The Latin version of the aphorism is written on a plaque above the Oracle's door in the Matrix film series, where it is rendered in a non-traditional Latin; that is to say temet nosce ("thine own self thou must know") translated in the Matrix as know thyself.
